Information recording apparatus, information recording method, information recording program and information recording medium

Abstract

An information recording apparatus encodes distributed information which is music information to be recorded distributed via a network in a specific encoding scheme for allowing decode by a plurality of types of information reproducing apparatuses, records the encoded music information and also records the distributed information as-is in a distribution method thereof, and further records address information indicating a position having the encoded music information recorded and address information indicating a position having the distributed information recorded as-is in the distribution method recorded. And when the distributed information is moved to the outside after being recorded, it deletes the address information corresponding to the moved distributed information.

What is claimed is:  
     
         1 . An information recording apparatus comprising: 
 an encoding device which encodes record information in a specific encoding scheme for allowing decode by a plurality of types of information reproducing apparatuses to generate encoded record information;    a first recording device which records the generated encoded record information on a recording medium;    a second recording device which records the record information as-is in an original encoding scheme thereof on the recording medium;    an address information recording device which records record address information including first address information indicating a position on the recording medium where the generated encoded record information is recorded and second address information indicating a position on the recording medium where the record information is recorded as-is in the original encoding scheme thereof; and    a deleting device which, at least when the record information recorded as-is in the original encoding scheme thereof is determined to be undetectable on the recording medium, deletes from the recording medium the record address information corresponding to the record information determined to be undetectable.    
     
     
         2 . The information recording apparatus according to  claim 1 , wherein, the record information is determined to be undetectable on the recording medium in the case where a process of deleting the record information from the recording medium is performed or a process of moving the record information from the recording medium to the outside is performed.  
     
     
         3 . The information recording apparatus according to  claim 1 , wherein, in the case where the record information is one other than record information distributed via a network, the address information recording device records invalidity information, indicating that the second address information is invalid, at the position on the recording medium at which the second address information should be recorded.  
     
     
         4 . The information recording apparatus according to  claim 1 , wherein the record information is distributed via a network in compliance with the SDMI (Secure Digital Music Initiative) specifications.  
     
     
         5 . An information recording method comprising: 
 an encoding process of encoding record information in a specific encoding scheme for allowing decode by a plurality of types of information reproducing apparatuses to generate encoded record information;    a first recording process of recording the generated encoded record information on a recording medium;    a second recording process of recording the record information as-is in an original encoding scheme thereof on the recording medium;    an address information recording process of recording record address information including first address information indicating a position on the recording medium where the generated encoded record information is recorded and second address information indicating a position on the recording medium where the record information is recorded as-is in the original encoding scheme thereof; and    a deleting process of, at least when the record information recorded as-is in the original encoding scheme thereof is determined to be undetectable from the recording medium, deletes from the recording medium the record address information corresponding to the information determined to be undetectable.    
     
     
         6 . A program embodied in a recording medium which can be read by a computer in an information recording apparatus, the program causing the computer to function as: 
 an encoding device which encodes record information in a specific encoding scheme for allowing decode by a plurality of types of information reproducing apparatuses to generate encoded record information;    a first recording device which records the generated encoded record information on a recording medium;    a second recording device which records the record information as-is in an original encoding scheme thereof on the recording medium;    an address information recording device which records record address information including first address information indicating a position on the recording medium where the generated encoded record information is recorded and second address information indicating a position on the recording medium where the record information is recorded as-is in the original encoding scheme thereof; and    a deleting device which, at least when the record information recorded as-is in the original encoding scheme thereof is determined to be undetectable on the recording medium, deletes from the recording medium the record address information corresponding to the record information determined to be undetectable.
